A Study of Multiparametric MRI and pHLIP® ICG in Breast Cancer Imaging During Surgery
The purpose of this study is to find out whether pre-operative mpMRI using additional MRI sequences may improve surgical outcomes by providing more accurate information about the extent and acidity of the tumor than standard MRI, and to see whether the use of the fluorescent imaging agent pHLIP ICG and NIRF imaging during surgery is a safe approach that may allow the surgeon to see the tumor and nearby tissues that contain cancer cells more clearly and remove them completely. During the Phase IIa part of this…

About this study
The purpose of this study is to find out whether pre-operative mpMRI using additional MRI sequences may improve surgical outcomes by providing more accurate information about the extent and acidity of the tumor than standard MRI, and to see whether the use of the fluorescent imaging agent pHLIP ICG and NIRF imaging during surgery is a safe approach that may allow the surgeon to see the tumor and nearby tissues that contain cancer cells more clearly and remove them completely. During the Phase IIa part of this study, the safe dose of pHLIP ICG will be used that makes it easy for the surgeon to see the tumor and the nearby tissues and structures that may contain cancer cells. This study is the first to test pHLIP ICG in people, and the first to test the use of pHLIP ICG with mpMRI and NIRF imaging in surgery for breast cancer.
Interventions
- Diagnostic Test: pHLIP® ICG NIRF imaging — Pre-operative research MRI will be performed 1-3 weeks prior to the surgery. single pHLIP® ICG injection will be administered i.v. by a radiologist on the protocol one day prior to scheduled surgery on the occasion of presurgical localization (12-36 hours prior to the surgery). In Phase I, we propose to investigate 4 different doses: Dose level 1 = 0.04 mg/kg Dose level 2 = 0.075 mg/kg Dose level 3 = 0.15 mg/kg Dose level 4 = 0.30 mg/kg In Phase IIa, the researchers propose to administer selected in Phase I dose of pHLIP® ICG. In Phase IIa, the researchers propose to administer pHLIP® ICG at DL2, DL3 or DL4 at different time points prior to surgery ranging from 12-110 hours, with targeted enrollment of 12 patients. Next, the selected optimal dose and timing will be used with targeted enrollment of 28 patients. The total number of subjects in Phase IIa study is 40.
Primary outcomes
- Dose-limiting toxicity (DLT) (15 days post pHLIP® ICG injection)
- Concordance between the absence of optical signal and histopathological confirmation of absence of malignancy. (Phase II) (1 year)
- Visualization of a lesion with pHLIP® ICG (Phase II) (up to 6 months)
